Advanced options
Ping speed
Ping speed controls the rate the transducer transmits the signal into
the water. By default, the ping speed is set to max. It may be
necessary to adjust the ping speed to limit interference.
Scroll speed
You can select the scrolling speed of the image on the screen. A
high scroll speed updates the image fast, while a low scroll speed
presents a longer history.
Ú
Note:
In certain conditions it may be necessary to adjust the
scroll speed to get a more useful image. Such as adjusting the
image to a faster speed when vertically fishing without moving.
Noise rejection
Signal interference from bilge pumps, engine vibration and air
bubbles can clutter the image.
The noise rejection option filters the signal interference and reduces
the on-screen clutter.
Surface clarity
Wave action, boat wakes, and temperature inversion can cause
onscreen clutter near the surface. The surface clarity option reduces
surface clutter by decreasing the sensitivity of the receiver near the
surface.
Colorline
Allows the user to adjust the colors of the display to help
differentiate softer targets from harder ones. Adjusting the Colorline
can help separate fish and important structures on or near the
bottom from the actual bottom.
Use the up and down Arrow keys to adjust the scroll bar.
Restore mode default
This menu option is available if you customize one or more settings.
When selected all the customized settings are changed back to the
default settings.
